Summary

THE DRAWBACK TO THE USUAL BREWERY CARBONATION SYSTEM IS THAT, AS THE CARBON DIOXIDE IS DRAWN FROM FERMENTING VATS IT CONTAINS CONSIDERABLE POLLUTANTS IN THE FORM OF NON-CONDENSIBLE GASES. THESE INCLUDE OXYGEN WHICH IS DIFFICULT TO SEPARATE FROM CO2 VAPOUR AND WHICH, IF PRESENT IN BOTTLED BEER AFTER CARBONATION, CAUSES OXIDATION AND TASTE DETERIORATION. THE SYSTEM DESCRIBED USES A NEW DESIGN OF CO2 CONDENSER IN WHICH CO2 TRAVELS UPWARDS THROUGH A TUBE IN TUBE HEAT EXCHANGER COOLED BY ANOTHER REFRIGERANT. THE CO2 VAPOUR BUBBLING THROUGH CONDENSED LIQUID IS < FLASH > CONDENSED AND NON-CONDENSIBLE GASES CONTINUE TO RISE TO THE TOP WHERE THEY CAN BE EFFICIENTLY PURGED. THE COOLED CONDENSED LIQUID TENDS TO TRAVEL DOWN THE TUBE SURFACE AND IS GATHERED IN A STILL-WELL BENEATH, FROM WHERE IT IS PASSED IN A REASONABLY PURE STATE TO STORAGE FOR BOTTLING LINES. D.W.H.
